Performing an absolute system reset from the rear panel

This function is identical to the front panel system reset (see Performing a system reset from the front panel on page 3-32) without requiring you to power down the switcher. This function is also identical to the Esc ZQQQ SIS command, see chapter 4, Programmer’s Guide). A system reset:

•Clears all ties and presets

•Clears all video and audio mutes

•Sets all input audio levels to unity gain (+0 dB)

•Sets all output volume levels to 100% (0 dB of attenuation)

NSystem reset does not replace any user-installed firmware.

Perform a system reset as follows:

1.	Use an Extron Tweeker to press and hold the Reset button until the rear panel
	Reset LED blinks three times (approximately 9 seconds) (figure 3-57).
